Beware of spoilers, both marked and unmarked!
Vigilantes of Naruhata
- Almighty Janitor: Despite what they've done for the city, and their advances in fighting against a lethal drug trade; the best exposure and recognition they've gotten are tabloids misprinting Koichi's hero name. Pop is the only one that the public has really noticed, and not for the right reasons. This works to their advantage, because legally they're considered villains no matter how heroic their actions, and a high enough profile for the pro heroes to notice their vigilantism would require said heroes to arrest them.
- Anti-Hero Team: They're all outlaws by default, as unauthorized Quirk usage is considered illegal, even if it's with good intentions like playing a hero. However, Knuckle Duster is the only one that really fits the mold.
- Clark Kenting: Against all odds they've managed to keep their identities a secret. Their costumes are things they threw together themselves rather than getting them from the Hero Association (which, to be fair, aren't big fans of anonymity either) and are varying levels of Paper-Thin Disguise. The only reason they haven't been investigated yet is because they're doing the bulk of the effort in taking down the Trigger addicts.
- Hero with Bad Publicity: Makoto's survey of the area shows that as far as the public is concerned, Knuckle Duster is either a scary troublemaker or unknown, "The Hauler" is well-intentioned but kind of creepy, and Pop☆Step has a nice butt. Pop☆Step's reputation grows more positive when she joins the FeatherHATS, and the same happens to Koichi as the series continues, but little changes for Knuckle Duster.
- Ragtag Bunch of Misfits: Their ranks consist of a college-level social outcast, a high-schooler moonlighting as a pop idol, and a Badass Normal 30-something man trying to be The Punisher.
- Vigilante Man: But of course. Knuckle Duster is far more overt about it than Koichi and Pop.
- Weak, but Skilled: Koichi and Kazuho have two of the weakest Quirks in the series offensively, having little-to-no combat potential and practicality, respectively. Meanwhile, Knuckle Duster is Quirkless, which is a huge handicap when Everyone is a Super. Doesn't stop them from trying, and it definitely doesn't stop them form winning.
Koichi Haimawari — Nice Guy/The Crawler
Debut: Chapter 0 (Illegals)
The hero of the story, a 19-year-old who wanted to be a hero, but missed his chance when he was young. After hours, he dons a costume and does "hero work" (really just self-imposed public services like giving out directions, delivering lost items, helping the elderly cross the street, and cleaning up trash), until an encounter with Knuckle Duster changes his life.
His Quirk is "Slide and Glide", which allows him to slide around at the speed of a bike when at least three of his limbs are touching the ground. There's a lot more to his Quirk than he thinks, and with added training and experience, Koichi starts to take the brakes off it to use for vigilantism.
- Accidental Misnaming: After changing his hero name, people still don't bother to remember it, calling him things like "The Hauler" or "The Cruller".
- Adorkable: Some of the smiles he makes as a result of Good Feels Good put him in this territory. Not to mention that he is an Extreme Doormat and an overall Nice Guy.
- Ascended Fanboy: Not nearly to the extent as Izuku, but Koichi is also a major fan of All Might, gaining an appreciation for doing little tasks for others without reward and later doing "hero" work as a vigilante.
- Berserk Button: He's a pretty mellow guy most of the time but he will not let anyone insult his costume. It's one of the few genuine things that can get him angry.
- Butt-Monkey: He gets beat up a lot, even by low-level villains. It doesn't help that his Quirk doesn't exactly have a lot of raw power to incapacitate others with, at least at first.
- Calling Your Attacks: Like a real pro-hero, he tries coming up with names for his moves and oh boy, does he fail so badly at it.
- Catchphrase: "I'm the man who (fill in the blank), The Crawler!"
- Civvie Spandex: His "hero costume" is simply one of his (many) All Might hoodies over motorcycle gear along with gloves and boots. He pulls his undershirt up to cover his mouth and (sometimes) uses a pair of shades to cover his eyes.
- Clark Kenting: The worst offender of the group, as his "costume" is just him wearing the hood of his All Might jacket, pulling his shirt up to cover the bottom of his face, and wearing tinted shades (which he rarely uses) to hide his eyes.
- Classical Anti-Hero: He's a bit cowardly and kinda lame, but he has the true spirit of a hero, even if he has to be a hero outside the law as a vigilante.
- Combat and Support: He and Pop are the support to Knuckle Duster's combat, getting civilians to safety and tripping up villains while their leader goes to town.
- Creepy Good: Seen as this by the populace, where the most positive reaction amounts to, "He's such a nice man! But he's still creepy." A high-school girl was convinced that Koichi was busy flipping skirts with his Quirk, while a third guy said that Koichi was still way too fishy to trust. This even extends to his civilian life, where his classmates shun him because of his early attempts to invite friends to his apartment in an abandoned building.
- Dangerous Forbidden Technique: His Shooty-Go-Blam, an offensive move he created using his Quirk. He talks it over with Pop and uses her reactions to gauge how much of it he should use even in emergencies. And then there's an additional layer of forbidden with the concentrated version that takes it from "annoyance" to "killing blow," which he firmly decides never to use.
- Darker and Edgier: Played with. Koichi tries to shed his "Nice Guy" persona reputation by reinventing himself as "The Crawler" despite not changing his appearance or mannerisms all that much. He does end up getting embroiled with much darker situations than littering, but he also keeps up the little acts of good.
- Didn't Think This Through: Once Knuckle Duster disappears and the "Next Level-Villains" starts popping up, he tries to take them on by himself without any real way to bring them down, resulting in a very annoyed Captain Celebrity who have to swoop in, clean up, and save him every time instead.
- The Everyman: His life was more or less normal since he didn't get into Hero School. At least, until he met Knuckle Duster...
- Exact Words: When Makoto gets a little too close to the truth about his identity, he manages to weasel his way out of her Living Lie Detector Quirk by the simple fact that she called him "The Hauler" much like the populace has been doing for a while. Since he sees himself as "The Crawler", he can blatantly say that he isn't "The Hauler" and pass her Quirk's test since he's telling the truth. Notably, Koichi isn't aware of her Quirk, so he did this completely unknowingly.
- Expy: The author's notes about Koichi in the first manga collection also point out one of the basic concepts for him is "Izuku Midoriya if he'd never met All Might." (See the entry for Foil for more details.)
- Extreme Doormat: Knuckle Duster and Pop☆Step pretty much invite themselves into his home without permission and he doesn't even bother trying to get them to leave. Not to mention the first technique he developed for his Quirk is a way to grovel without getting kicked.
- Fan Boy: Of All Might, having looked up to him since he was a child. Koichi is particularly proud of his collection of All Might hoodies, of which there were several re-releases that look virtually identical, but he's able to tell them apart with ease. These same hoodies are also used as part of his vigilante costume. And he thinks that wearing an All Might hoodie makes him more effective as a vigilante, but only if it's official merchandise.
- Flight: While trying to save himself and Makoto from a lethal fall, he manages to propel himself in mid-air enough for Ingenium to save them. According to his mother he was able to do this when he was a baby, but out of concern for his safety she conditioned him to stop using his Quirk that way by punishing him whenever he did, so by the time he grew up he completely forgot that he could.
- Foil: A good one towards Izuku. Both start out as weak and wanting to be heroes. However whereas Izuku is intelligent and can figure out the true potential in most Quirks and started out without one, Koichi was born with one, but never even tried to experiment with it and needed other people to point out how to use it. This goes all the way down to their appearances too. While Izuku has a head of striking green Messy Hair, Youthful Freckles, and is ripped for his age due to his intense training, Koichi is fair, tall and lanky with short, normal brown hair due to his relatively mundane lifestyle. Their costumes are both based on All Mights and are characterized by a trademark hood. But while Izuku rarely wears his, Koichi often has his up. One of the author's concepts for Koichi is that as a college student, he's not a boy despite not being an adult yet.
- Forgotten First Meeting: Actually saved Pop from drowning as a little girl on the way to his High School Entrance Exam. But he thought she was a little boy, and was in too much of a hurry after the rescue to note otherwise.
- Fragile Speedster: After getting some tips from Ingenium, Koichi is able to keep up with the Turbo Hero himself but has even better maneuverability as well as the ability to go straight up walls. His overall fighting strength hasn't changed much though and he's still relegated to mostly tripping up opponents and distracting them rather than outright fighting them.
- Future Badass: Subverted. His monologue post-Knuckle Duster's disappearance is similar to Izuku's, but instead of talking about how he becomes a great hero, he claims that he matures into a respected if relatively minor local vigilante.
- Giver of Lame Names: Neither of his vigilante names are particularly impressive and people have trouble remembering "The Crawler" and misname him repeatedly. Then there's the name of his "ultimate move".Koichi: Ultimate rapid-fire combo... The Crawler's Shooty-Go-Blam-Blam-Blam-Blam-Blam!
- Good Feels Good: Is genuinely gratified by the little things he does for others, being the primary reason he's stuck around with his group despite the fact that it's illegal.Koichi: [To Pop-Step while cleaning up a park] "I'll stop picking up trash because it's uncool?" That just doesn't feel right. That's not the kind of man I am.
- Hand Blast: By accidental coincidence while using his powers, he discover that his Quirk isn't restricted to three contact points in the ground to set off, allowing him to fire off the repulse force from his free palms like shockwaves akin of shotgun blasts as a result.
- I Just Want to Be Badass: Even knowing it's too late for him now, he still dreams of being a real hero, just for once in his life.
- Koichi tried to get into a hero school, but didn't get to the exam on time because he was busy saving someone. So he didn't get to become a hero because he was being a hero. Also the person whose life he saved turned out to be Pop☆Step.
- He mentions hoping to get a girlfriend once in college, but never could due to his (misunderstood) reputation as a creep. Now that he's a vigilante, several women have shown attraction to him, and he's completely unaware of it all.
- Innocently Insensitive: He's a Nice Guy at heart, but he has a habit of being unintentionally rude. Throughout the arc where Pop☆Step is set to perform on stage as part of an ensemble act, Koichi keeps blurting out comments about the captain of the dance squad who are taking part. Not only do these comments tend to be unintentionally insulting, but he keeps inadvertently preventing a guy who has a crush on her from giving her compliments.
- In the Hood: His "Hero" costume is just a hoodie with bunny ears on it. Many people just mistake him for a All Might cosplayer. Turns out he has quite a few as part of a collection of Annual All Might Hoodies.
- Lethal Harmless Powers: His Shooty-Go-Blam isn't very impressive, but that's mostly because he uses it as a distraction rather than a genuine attack. When he wants to, he can concentrate the area repelled to a pinprick capable of punching straight through metal cans, or even a person.
- Let's Get Dangerous!: After Queen Bee takes over Pop, he takes off his self-imposed restrictions to take them down by any means necessary.
- Logical Weakness: His quirk allows him to repel objects from his hands and feet and also reverse the force to stick to surfaces. This means that he can anchor himself to whatever he's standing on and use the repelling force of his palms as mini-shields that allow him to defect blows or objects. However, all of this is dependent on his weight and strength so anything too big or heavy for him to stop, he can only deflect or alter the course not stop it.
- Meaningful Rename: He was originally called "Nice Guy" when his "heroism" consisted of small acts of public service. After he joined up with Knuckle Duster and started actually trying to fight criminals, he changed his hero name to "The Crawler".
- More Powered Protégé: To Knuckleduster. Despite the latter being Quirkless, he provides Koichi with a lot of guidance on the basics of being a vigilante hero, most notably hand-to-hand combat and detective work.
- Nice Guy: It was his original vigilante name to begin with for a reason! Even after becoming "The Crawler", he still goes out of his way to help others for no benefit to himself by keeping kids from getting into the street, cleaning up after others and reminding them not to litter, giving people rides to work, and handing a man the lunch he forgot to pack at the behest of the man's wife.
- No Good Deed Goes Unpunished: Koichi didn't fail to get into Hero School due to a lack of merit or a bad Quirk, he failed to get in because he was late to the exam because he too busy trying to be a hero by saving a child who had fallen into the river, thus making him unable to take the test to enter Hero School.
- Oblivious to Love: He's extremely dense and fails to notice romantic cues, which often results in him blurting out insensitive comments to his secret admirer and other couples-in-progress.
- Refusal of the Call: Knuckle Duster offers to let him partner up to fight against criminals. But after getting a taste of what real hero action is like, Koichi initially refuses.
- Required Secondary Powers: He can speed up his glide but he can't slow down, which is why he usually stays at a manageable bicycle speed. It's not until he obtains protective motorcycling gear and learns how to fall safely that Koichi starts going faster. It's eventually subverted when it's pointed out he can slow down by just going backwards, then a deconstruction as his Quirk limitations are due to his lack of training and experimentation to find its true potential.
- Ridiculously Average Guy: Surprisingly enough for a main character. While he's not incredibly attractive, he not a Gonk either, just very average looking. Then again, he was an average guy until Knuckle Duster offered him a chance to be a hero.
- Running Gag: Everyone except Pop☆Step and Knuckle Duster get his vigilante name wrong after he changes it to "The Crawler", with the general populace referring to him as "The Hauler". The only ones who do get his name right also happen to be villains who have developed a vendetta against him, though he's still happy that someone actually remembered.
- Spider-Man Send-Up: Greatly resembles Peter Parker and his civilian life due to how life has a tendency to browbeat him. Likewise, his sliding pose resembles Spider-Man's wall crawl, is referenced as a bug, and discovers he can use his powers to stick directly to walls, just as Spidey does. His In the Name of the Moon Mad Libs Catch Phrase is also a Shout-Out to Spider-Man (Japan) (although Koichi has yet to call himself an "Emissary from Hell").
- Super Speed: His Quirk allows him to move very quickly when he wants to, even up walls if he has enough momentum. More impressive is his maneuverability, as changing the direction of his propulsion allows him to make hairpin turns more conventional speed Quirks can't match.
- Swiss-Army Superpower: While initially seeming quite limited, his Quirk is eventually revealed to be this. With it, he can move incredibly fast, slide around walls, fire Hand Blasts, and even fly, he just needed to experiment with it a little more.
- Technical Pacifist: Despite wanting to be a hero, he shrinks at the first sign of mortal danger, and his definition of heroing is just doing public services, like picking up trash or pointing out directions to people. He gets into far more life-threatening situations as he continues his vigilante activities, but even then he rarely dishes out serious harm, tripping up people at worst. He starts fighting more later into the series.
- Took a Level in Badass: Hard to see since his mannerisms remain largely the same, but comparing his use of his Quirk in the first few chapters to later ones shows he's gotten significantly better at using it, not to mention that his heroism expands from to self-imposed community service to fighting villains.
- Wake Up, Go to School, Save the World: Played with. While Koichi is rarely engaging in life-changing events, his vigilante work is reflecting on his grades, forcing him to ask for help from his upperclassman... one of whom happens to be the sister of Officer Tsukauchi.
- Wall Crawl: Discovers that he can use his Quirk to glide up vertical surfaces early in the series. Later, he finds that he can also use it to cling to surfaces without propelling himself.
- What Kind of Lame Power Is Heart, Anyway?: His Quirk lets him move around at the speed of a bike, and he has to take a crawling pose for it to work. Actually using it gets him chewed out by a policeman. In battle, he figures he can go for his opponents' knees, but he doesn't have the strength or experience to pull it off. However...
- Heart Is an Awesome Power: As it turns out, his Quirk works by him repelling force with his palms, meaning his gliding is just him controlling the direction the force is repelled. He can also invert the force so that instead of pushing things, he pulls them in, allowing him to Wall Crawl on vertical surfaces. He later learns that he can cling to walls without moving as well. Using his Quirk, he can glide at great speeds, though he had trouble going too fast since he couldn't brake... that is, until Tensei Iida crossed his path and advised him on how to brake. Now, he can go fast enough to catch up with a speeding bus while also having enough maneuverability to make hairpin turns and slide through narrow alleyways without bumping into anyone. Koichi can also outright fly with his Quirk, as he can use air as his points of contact. He was able to do it far more easily as an infant, but his mother feared for his safety and punished him every time he tried to do so until he forgot. Then he discovers he can use his Quirk to fire Hand Blasts! Basically, he can use the repelling force to fire off invisible blasts of force at opponents. Basically, "Slide and Glide" is a way better Quirk then he originally gave it credit for.
- Willfully Weak:
- Koichi's unimpressive use of his Quirk in early chapters is not because that's the full extent of his abilities. He can go a lot faster, but loses control if he goes too fast and would break rules which forbid reckless use of Quirks in public, already treading a thin line when he uses his with caution because there are strict regulations on transport-based Quirks like his. He also had plans to become an official pro hero, but they got derailed and he found himself stuck in mediocrity, so he was never really encouraged to go beyond his limits until circumstances changed.
- After he develops his Shooty-Go-Blam technique, he demonstrates it at different levels of power to Pop, then uses her reactions as a metric for what amount of pwoer is acceptable. So while his usual usage of it isn't much more powerful than a light tap and can range up to the equivalent of a solid punch if he wants to, he can go stronger then that. Much stronger.
Kazuho Haneyama — Pop☆Step
Debut: Chapter 0 (Illegals)
A girl who fashions herself as a Pop Idol and does "Guerilla Concerts" in public. Her Quirk is Leap, which allows her the ability to jump high into the air as long as she can touch a foothold.
- Attention Whore: Intentionally just a self-proclaimed Idol for fame and whatnot.
- Cannot Spit It Out: She has feelings for Koichi, starting with when he rescued her from drowning. After the timeskip, it's revealed that she's been basically living with him for a few years without ever telling him that. It gets worse when she overhears Makoto propose a committed relationship; she spends the next few weeks avoiding having the conversation with Koichi even though they both know she needs to. Eventually, she breaks down and calls Rokuro for emotional support... and he turns her into the next Queen Bee.
- Clark Kenting: She's a plain-looking schoolgirl when she's not wearing her costume, complete with glasses.
- Cleavage Window: Her leotard has a small heart-shaped window to show her cleavage.
- Distressed Damsel: Ended up bumping into the punks Koichi gained the ire of earlier who seriously were considering harming her and exposing her identity to the internet. Likewise ends up being caught by a drug dealer turned giant monster in the second chapter.
- Expy: Series author Hideyuki Furuhashi explicitly compared her to the heroine from the Shadow Lady manga while meeting with his editor to plan the series. (Later, the series artist originally decided not to have the wings on her back to keep the resemblance from being too obvious — and Furuhashi asked him to put wings on anyway. "The guy knows what he wants!")
- FaceMonster Turn: Pop is kidnapped and turned into the new host of the Queen Bee.
- Favors for the Sexy: Utilizes her fanbase in this way to get intel, as they're more than happy to share anything with her.
- Green-Eyed Monster: Starts to get this way once Makoto Tsukauchi enters the picture and starts spending time around Koichi.
- Jerk with a Heart of Gold: She's somewhat nice, thanking Koichi for warning her of the cops that have come to break up her show. But then she starts showcasing her rude side, about commenting how lame his costume is, and trying to coax him into being her security. And by coax we mean demand...for free.
- In a Single Bound: She uses her Quirk to "jump" in the in air as long as she has a foothold to jump from.
- Jump Physics: Her Leap Quirk cushions any landing from her jumps, but only from her jumps, so she's still at risk from falls. She also needs a solid foothold to start from, making jumps from non-solid surfaces like sand difficult to impossible.
- Leotard of Power: Her hero costume is essentially a high-cut leotard with a very short skirt worn over it.
- Magic Idol Singer: How she fashions herself, anyway. It's unknown if she's truly trying to be a hero or just to get noticed.
- Mission Control: Since she has the least combat ability out of the trio, she spends most fights gathering information and being an eye in the sky to the others.
- Nominal Hero: While Koichi and Knuckle Duster became vigilantes to do good, Pop☆Step doesn't have a reason to join and will admit she's not part of the group to anyone that asks. It's later implied she joined to stay with her childhood rescuer Koichi and repay the favor by helping him.
- Pretty Freeloader: Starts crashing at Koichi's place without permission.
- Rescue Romance: Was saved from drowning as a little girl, and grew up with a case of Hero Worship for her rescuer Koichi.
- Shameless Fanservice Girl: Wears a revealing leotard and a very short skirt, does all her performances in the air and apparently has no problems with showing people her ass as she does it. She becomes infamous to the point that even young children are noting how she has a "bouncy butt".
- She Cleans Up Nicely: As Kazuho, she's a frumpy-looking student, but as Pop☆Step she's very attractive to the point of having her own fanbase.
- Tsundere: As Koichi puts it, "she can't bring herself to apologize," and tends to hurl insults or accusations at people instead of being honest with her feelings. She especially becomes one around the person who rescued her as a child.
- Women Are Wiser: While Koichi is often either trying to control or getting dragged along by Knuckle Duster, Pop is usually the one getting the right info.
Iwao Oguro — Knuckle Duster
Debut: Chapter 0 (Illegals)
A Quirkless vigilante who goes on the prowl for criminals at night. He seemingly retired from vigilantism after defeating Kuin and saving his daughter, but in actuality, he traveled to Hong Kong, China to learn more about Trigger.
Before the series began, he served as a hero called O'clock. He possessed an acceleration Quirk called "Overclock" that allowed him to move incredibly quickly in short bursts. He fell out of public view a few years before the series began and was even thought to have died, but he really just went into hiding after something resulted in him losing said Quirk, forcing him to become a Quirkless vigilante.
- 555: His "business card" is full of fake information, among them a phone number which consists of XXX-XXXX-XXXX. The rest of the information, including the address and zip-code, is similarly cryptic. Nevertheless, his smooth presentation prevents Koichi's mom from suspecting a thing. Said presentation foreshadows his past as a Pro Hero, as he would have had to do this on a regular basis to promote himself.
- '90s Anti-Hero: Fashioned after them, and his overall attitude certainly has brings this to mind.
- Archnemesis Dad: Seems to be this to Kuin Hachisuka, but it's a bit more complex then that. Kuin is using Tamao Oguro, his actual daughter, as a host body. So, while elements of Tamao's memory and personality are still active, the consciousness currently known as Kuin Hachisuka is driven by the Queen Bee attached to her brain.
- Badass Beard: He gains a rather glorious one when he returns in Chapter 44, though he shaves it off soon after.
- Batman Parody: Of Batman but without the tools, as the author admits. He has the gruff demeanour of being a Badass Normal Terror Hero who fights crime at night. He's also reminiscent of the DC character Wildcat, being an aging non-superpowered brawler.
- Beneath the Mask: Underneath his Blood Knight '90s Anti-Hero exterior, he's a loving father and husband who holds a deep grudge against the people who hurt his family.
- Big Damn Heroes:
- Arrives to save Koichi and Pop☆Step from a couple of thugs.
- Does it again, saving Koichi from Stendhal.
- Badass Normal: He's Quirkless, but he's strong enough to send foes flying into walls, regually tangles with villains juiced up on Quirk-enhancing drug, manages to go toe-to-toe with Eraserhead, a pro hero, as well as Stendhal, who would later go on to become the Hero Killer Stain.
- Blood Knight: He loves to fight against villains who can actually pose a challenge to him.
- Borrowed Catchphrase: Liberally uses All Might's "I am here!" catchphrase when he either arrives onto the scene inelegantly or when he's about to sneak attack someone in a decidedly unheroic fashion. He also uses it outside of his vigilantism in more dramatic and heartfelt fashions, like when he assures his daughter that he isn't going to leave her.
- Boxing Battler: He fights using fisticuffs augmented by knuckle dusters and is shown training Koichi with focus pads.
- Brought Down to Badass: He used to be the super-fast Pro Hero, O'clock, but at some point his Quirk was stolen and he got his signature facial scar.
- Charles Atlas Superpower: He's a Badass Normal to the point he can overpower a physical Quirk user in sheer brute force.
- Cleans Up Nicely: Most of the time he's either in his vigilante outfit or bumming around with Koichi. When he first meets Makoto and Koichi's mother, though, he shows up wearing a suit from his day job and completely masks his Blood Knight traits. As a result, even with the huge scar on his face, he comes across as suave and rugged instead of the scary guy he's usually presented as.
- Combat Pragmatist: His fists are usually good enough to handle most of the villains he faces, but when facing a serious opponent like Stendahl or Kuin, he has no problem whatsoever with using any means at hand to catch them off guard.
- The Cowl: Contrasting to All Might's Cape. He's a vigilante in his world's laws, but is more than willing to go out and be a hero after dark, when All Might isn't around and try to inspire others to do the same.
- Crutch Character: Unhinged as he is, early in their vigilante careers, his allies need his raw strength, life experience, and drive. So naturally, he leaves right when their challenges are getting even greater.
- Curb-Stomp Battle: Pretty much every fight he's in is this for the other party. Knuckle Duster brings Badass Normal to a level rarely seen.
- Exact Words:
- During his encounter with Stendhal, he lays down a line of wire and tells the killer that he'll punch him if he steps over it. When Stendhal gets close, Knuckle Duster steps over the line and lays him out flat, pointing out that he never said that he wouldn't cross the line himself.
- The description that he gives Koichi's mother and Makoto of the "community service" he and Koichi do is also full of this.
- Expy: Aside from being a Batman Parody.
- Design-wise, he appears to be one of The Punisher with a bit of Marv thrown in.
- Of The Tick, a boisterous brawler with a strong (and destructive) sense of justice who takes under his wing a neurotic youth who has a pointy "eared" costume and the power of flight.
- As O'clock, he was one to The Flash, being a speedster hero capable of moving faster than the eye could perceive.
- Foil: Like Koichi to Midoriya, he can be considered the spin-off's version of All Might. All Might is introduced when he dramatically appears on a sunny day, introduces himself before effortlessly defeating a powerful supervillain in one blow to save the adoring main character; Knuckle Duster is introduced when he awkwardly appears out of a dumpster in the middle of the night, introduces himself before laboriously beating the shit out of some teenagers for longer than necessary to save the terrified main character. All Might has a 100% Adoration Rating; Knuckle Duster is a Hero with Bad Publicity. AM stays in the hero business for as long as his body will let him; KD accomplishes his goal and then retires from vigilante work for months. And of course: Toshinori was born Quirkless but was gifted power as a young man; Oguro was born with a powerful Quirk but had it taken from him as a young man.
- Hero with an F in Good: Tends to veer into this territory at times for comedic effect thanks to his "beat up every suspicious person in sight and sort out the details later" attitude, forcing Koichi to hold him back before he goes too far.
- I Have Many Names: In addition to his civilian identity and vigilante identity, he used to go by the name "O'clock" as a Pro-Hero, but only in Japan. In Hong Kong, he was known as "Ciupan Seikyun" (Hyper Quadfist). He uses the fake name "Takeshi Kuroiwa" occasionally.
- It's Personal: His crusade against the Villain Factory is this in multiple ways. Firstly, it's heavily implied the Villain Factory hospitalized his wife in a near-vegetative state, eventually leading to her death. Secondly, Kuin took over his daughter Tamao's body and mind to use as a puppet. Finally, Number 6 of the Villain Factory is obsessed with him and trying to take his old hero identity for himself.
- Loophole Abuse: Once Eraserhead realizes that he's Quirkless, he stops fighting him because if he isn't using a Quirk for illegal activities, then he falls outside hero jurisdiction.
- Meaningful Echo: His first line of dialogue during his introduction in chapter 1 mirrors his last line of dialogue during his reintroduction in chapter 44.Chapter 1: You punks... Did I hear you mention All Might? Well He ain't coming. But... I'm Here!!
Chapter 44: No you're right. That guy... Died a long, long time ago. Nevertheless... I'm Here.
- Meaningful Name: Knuckle Duster's main weapons are a pair of knuckle dusters.
- The Mentor: To Koichi, training him to be a hero outside the laws of their world. Number 6 wants him to be this to him, but Knuckle Duster isn't into the idea.
- Metaphorically True: After meeting Koichi's mom, he presents a business card with his name and "company", which, "provides support in neighborhoods like East Naruhata, where local government and community organizations are less effective.... keeps the roads clean and patrols for crime at night". It isn't technically false, but it's omitting a lot of details about how he's doing these things.
- Mooching Master: He and Pop decide that Koichi's apartment is their new base of operations without asking first. They also frequently raid his fridge or sleep on his couch.
- Nice Job Breaking It, Hero!: He winds up inspiring Stain's ideology after mocking "Stendhal's" lack of resolve, having easily knocked the murderous vigilante flat on his ass.
- Not So Similar: Completely rejects Stendhal when he tries to invoke Not So Different on him. They may both be pro-heroes-turned-vigilantes but whereas Knuckle Duster had to change his methods to continue the same job, Stendhal uses the same methods to hunt heroes that he used to use hunting villains.Knuckle Duster: Me? The same as you? Don't make me laugh. I'm a badass champion of justice, and you're nothin' but an insane street murderer!
- Only Known by Their Nickname: His teammates only call him by his hero name or other nicknames, like "old man" or "master". When he introduced himself to Koichi's mother, he acted surprised that Knuckle Duster actually had a real name, unaware that even that was an alias.
- A Pupil of Mine Until He Turned to Evil: It's implied that he mentored Number 6 of the Villain Factory on account of their similar Quirks before the young man ended up becoming a villain, though this isn't exactly true.
- Red Baron: The Fist Janitor.
- Retired Badass: Retires from being a vigilante after he managed to save his daughter, though it's short-lived.
- Scars Are Forever: Has a gash on the left side of his face. He gained this gash on his last night as O'clock after a bad crash.
- Thou Shalt Not Kill: Averted, surprisingly. In a series where heroes try their best to not kill the villains but instead capture them and bring them to justice, Knuckleduster is one willing to advocate killing the villain if need be. He crushed the Queen Bee after freeing his daughter Tamao from it, and attempted to kill Number 6 via head shot with a sniper rifle, only missing due to a bird messing him up, and then tried to blow himself and Number 6 up just to get rid of him.
- When All You Have Is a Hammer...: He has a pair of knuckle dusters and that's it, and he uses it for everything from fighting criminals to interrogating civilians, much to Koichi and Pop☆Step's chagrin. Doesn't stop him from being a badass in any way.
- Would Hit a Girl: Has no problem whatsoever with punching Kuin in the face while she's using his own daughter's body no less because he knows he can't do any less if he wants to stop her.
Chizome Akaguro — Stendhal
Debut: Chapter 9 (Illegals)
Another vigilante that Crawler and Pop☆Step meet while chasing down a villain. Stendhal functions as a Serial Killer vigilante, targeting villains and killing them so they can't cause more trouble. For tropes regarding his current identity, see his entry here.
- '90s Anti-Hero: Acts like one, mercilessly killing the villains he targets.
- Anti-Hero: Unlike Knuckle Duster, he's not afraid to kill if he has to.
- Charles Atlas Superpower: His Quirk isn't why he can pull off all those ninja-like sword techniques. He spent all that time training because Bloodcurdle needs to injure the target first in order to work.
- Cynicism Catalyst: For a time he performed work as a Serial Killer vigilante, killing any villains he could find to accomplish what he felt the heroes couldn't. After losing to Knuckle Duster and being called out on lacking resolve, he heeded Knuckle Duster's words and resolved to instead target the false heroes he despised, becoming the Hero Killer Stain.
- Dramatic Irony: The first thing he says to Koichi is that he's a guy who likes to stick his nose where it doesn't belong. Years later he would hear these same words from a hero in training named Midoriya Izuku. And then he goes and actually cuts off his own nose, making it so that he doesn't have anything to stick where it doesn't belong.
- Establishing Character Moment: Cleaving a bad guy in half. Then, coldly walking away with the man's blood all over him without bothering to wipe it off as he continued to thumb through pictures of people on his hit list.
- Eye Scream: One of his favored tactics is going right for the eyes with his switchblades. Against those with bad reflexes, it works to horrifying effect, but to those experienced in combat, they are able to react in time to avoid having their eyes gouged out.
- Foreshadowing: From his outfit, weapons, and hard stances demeanor, it's heavily implied from the outset that this is Stain before he reached his Cynicism Catalyst with the hero world.
- After having his mask destroyed, he claims it is wrong to wear one. As Stain, he uses a Domino Mask to cover up his lack of a nose.
- Part of his Knight Templar behavior is that associating with a villain makes you just as bad as one. Yet he associates with Kuin Hachisuka, a representative of the Villain Factory, for quite some time during his crusade.
- Knight Templar: Merely associating with a villain, no matter how tenuous, makes you just as bad as a villain, according to him. No mercy will be spared.
- A Lighter Shade of Black: While he is called a vigilante, he's more akin to a Serial Killer with how often his crusades end in murdering the villains he fights. Despite this, he still is pursuing his own warped sense of justice, in comparison to the Villain Factory simply aiming to pursue their own goals. Makes sense considering who he grows into.
- Meaningful Name: The name Stendhal, and his real name Chizome Akaguro, refers to the colors red and black. He associates red to life and black to death, and strives to sever the gap between the two, meaning that he holds the power of life and death in his hands.
- Ninja: He dresses and fights like one, preferring bladed weapons while moving extremely quickly.
- Pay Evil unto Evil: Being a villain is cause enough to be killed, even if the said villain has never killed anyone.
- Self-Harm: After deciding that it is cowardly to wear a mask and that he needs resolve to remember that, he saws off his own nose with a trench knife to make it impossible to ever wear another mask. This willful disfigurement completes his evolution into Stain, plopping the discarded flesh in a sink and wandering down an alleyway muttering like a neurotic. It also shows that the dude is extremely imbalanced.
- Serial Killer: Although he is a vigilante, he works more like one of these, specifically targeting villains. After losing to Knuckle Duster, he would forgo killing villains and shift his focus to becoming a Hero Killer, taking on the identity of Stain.
- Teeth-Clenched Teamwork: He lets Kuin know one day he will come to kill her despite being the source for his information.
- Two Aliases, One Character: Stendhal is the original alias of Chizome Akaguro, before he discarded it in favor of becoming the Hero Killer Stain.
Major Pro Heroes
Christopher Skyline — Captain Celebrity
Debut: Chapter 14 (Illegals)
A high-ranking American pro hero, whose Playboy attitude landed him into so many scandals and lawsuits that he had to relocate to Japan just to find work.
His Quirk is "Flight" and it allows him to levitate and fly at high speeds.
- Attention Whore: In the hero business completely for fame and nothing else. Heck, his hero name is Captain Celebrity. He even has a theme song played during fights and rescues.
- Character Development: Due to Makoto's interference and his son's birth, he goes from being Jerkass who sleeps around and cares about fame to a legitimately heroic figure whose so enamored with his wife and son that he embarrasses them without realizing it.
- Curbstomp Battle: His Attention Whore tendencies and desire to make a show out of every fight he picks is the only reason any villain lasts longer than a few seconds against him.
- The Dreaded: His ex-wife Pamela is this to him. When Makoto ends up calling her during an interview, his demeanor turns a complete 180 and he becomes utterly terrified.
- Eagleland: A very interesting example that's played with. On the one hand, he fits the stereotypical Type II, being a loud, boisterous, obnoxious and glory-seeking American. On the other hand, it was all those traits that pretty much got him kicked out of the hero system in the US in the first place.
- Elemental Barrier: His Quirk covers himself and those he touches in an aerodynamic barrier. The barrier protects from heat, cold and physical harm. He can control whether himself or whomever he is touching would get the most protection from it.
- Expy: Between his Attention Whore attitude, blonde hair, the star on his chest, and his visor, he's a dead ringer for Booster Gold. He gains Gold's positive traits after going through Character Development.
- Flying Brick: His Quirk gives him the ability to fly and he's strong enough to carry an entire cruise ship over his head. In essence, his Quirk is similar to the powers of the 90's Superboy who initially had a singular power of tactile telekinesis, which was able to use to emulate several of Superman's powers such as flight and super strength.
- Glory Hound: He tries to gather as much fame and glory as possible, though he will give credit where it is due.
- Jerkass: In his first few appearances, he was nothing but an Attention Whore who wouldn't act unless there was a camera watch. He was so bad that he had to leave America to find work! Thankfully subverted later on, as he gets better with the help of Makoto and eventually drops a lot of the characteristics that made him so bad initially.
- Jerkass Has a Point: After rescuing Koichi from a villain, Captain Celebrity complains that he's not getting paid for it. Koichi and Kazuho point out they're not getting paid for their hero work either, but Captain Celebrity responds by pointing out that to them, it's more like a hobby, but to him, it's his job. In general, he normally gives good rationalizations for his seeming lack of professionalism, reminding readers that for all his showboating he's a very experienced and competent hero.
- Jerk with a Heart of Gold: In the later chapters he's revealed to be good with kids and loves his wife. He's even willing to put his own life at risk to save civilians.
- Lantern Jaw of Justice: And how! His cleft chin juts out even further than All Might's.
- Open Mouth, Insert Foot: Later chapters have Makoto imply that a lot of his apparent harassment back home was more a case of this than any genuine malice on his part. He then proceeds to demonstrate by saying several well-meaning, but easily misunderstood and incriminating things almost immediately.
- Pet the Dog: He might've been a total jerk at one point, but he was genuine when he complimented Koichi on rescuing a child's dog while he was busy fighting a villain. He was also genuinely nice to his fans and was still willing to risk his life to save people.
- Reality Ensues:
- He's gotten in trouble due to his attitude and had lawsuits filed against him. So much so, it's the reason he's in Japan in the first place as he couldn't find work in America anymore. Knuckle Duster even cites he's been given the nickname "Captain Troublemaker".
- A lot of these lawsuits were from women he flirted with. So much so, his ex-wife has pretty much made a business in their lawsuits against him.
- Really Gets Around: He's known as a philandering playboy to have gotten the name "Flying Stallion", which has resulted in multiple lawsuits involving his wife.
- Smug Super: While overall competent as a hero, he's in it for the glory and adulation.
The Trigger Investigation
Debut: Chapter 5 (Illegals)
A detective on the police force, and the lead investigator of the Trigger outbreaks.
- Friend on the Force: Turns out to be one for Knuckle Duster.
- Good Smoking, Evil Smoking: He's a smoker and a cop.
- Small Role, Big Impact: He sent Tsukauchi to request All Might's help in dealing with the Trigger outbreak, specifically telling him to talk to his secretary-manager, Toshinori Yagi, if All Might wasn't available. This situation led to Tsukauchi learning that Toshinori Yagi IS All Might, just in his skinny form, and led to him and All Might becoming friends.
A detective from the main series. In Vigilante, he works as an investigator for the Trigger Incidents, which leads to him and All Might's first meeting.
- See his entry here.
Shota Aizawa — Eraserhead
A Pro Hero from the main series. Since Vigilante takes place a few years before the main series begins, he has yet to take his job teaching at U.A. and is working as a normal hero. He assists in investigating the Trigger Incidents and acts as something of a mentor to Koichi on occasion.
- See his entry here.
Debut: Chapter 1 (Illegals)
A violent thug who crosses paths with the vigilantes on occasion. Initially just an antagonist, he eventually becomes a close ally to the vigilantes, namely Knuckle Duster. His Quirk, "Spikes", enables him to produce spikes from his body.
- Berserk Button: Due to past trauma, he absolutely hates it when people laugh at him.
- The Bully: What he is initially presented as, though this wasn't always the case, as he once wanted to be a hero too. He drops this after Knuckle Duster recruits him into helping find Tamao, and later becomes her bedside aide.
- Chekhov's Gunman: Seemingly a minor antagonist at first, but has a bigger role than initially perceived.
- Easily Forgiven: Played with. Koichi has no problem with him even after the whole attempted murder thing and Knuckle Duster comes to trust him as an ally, but Pop☆Step still hates him for what he tried to do to her.
- Face of a Thug: Granted, he is a thug in the present day, but in the past, he actually had noble ideals, and he cares for his friends enough to fight Stendhal alone.
- Foil: Is one for Koichi, specifically as a dark reflection of what Koichi might have become if he were shunned by society more harshly. Both are young men who are judged harshly on their appearance and who wanted to be heroes but were unable to.
- HeelFace Turn: After being saved by Koichi and Knuckle Duster from Stendhal, Knuckle Duster employs him as an informant in the search for Knuckle Dusters' daughter's whereabouts. After Tamao is freed from Kuin's control, Soga and his friends watch over her bedside whenever Knuckle Duster is out.
- Hidden Depths: One of his friends says that Soga wanted to become a hero too, and despite his Face of a Thug, he's shown to be rather sensitive to people laughing at him. Flashbacks show that people were constantly writing him off based on his appearance, leading him to become what they decried him as. Rapt reveals in Chapter 45 that he used to play guitar up until it destroyed in a fight too.
- Irony: During his clash against Stendhal, he was so enraged by Kuin mocking him that he starts screaming as he reminisces the many times in the past that he was rejected and ridiculed. As his brief tirade goes on, he yells that he is being treated as if he were some monster - almost simultaneously as he is transforming into a porcupine-like appearance.
- Lesser of Two Evils: He's an attempted murderer and all-around a violent asshole, but he's nowhere near as irredeemable as the more dedicated villains in the series, such as Kuin or Stendhal. This gets subverted once he undergoes a HeelFace Turn, showing off some of his Hidden Depths and acting more like a Jerk with a Heart of Gold.
- One-Winged Angel: After getting overdosed on Trigger, forcefully administered into him by Kuin, he transforms into a monstrous human-sized porcupine as he rages on. The transformation eventually wears off, however.
- Reformed, but Not Tamed: In the first chapter he planed to beat/stab Koichi to death, assaulted and threatened to rape Pop☆Step, and destroyed a store. After receiving a beating from Knuckle Duster and getting victimized by stronger villains like Kuin and Stendhal, he turns around into an informant and ally of Knuckle Duster, though he keeps his punk-ish traits.
- Spikes of Villainy: An antagonist with the power to create spikes from his body. Subverted after his HeelFace Turn.
- Spiky Hair: Fittingly enough for a punk with Spike-based Quirk.
- Then Let Me Be Evil: The reason why he is the way he is today. Despite initially wanting to be a hero as a child, years of mistreatment due to his appearance and his Quirk have made him into the punk he is today. He drops this, however, after he's saved from Stendhal by Koichi and Knuckle Duster.
- True Companions: With Rapt and Moyuru. He cares for them enough to fight Stendhal alone to keep them safe. After being made to watch over Tamao, she slowly becomes one for him too.
Moyuru Tochi and Rapt Tokage
Debut: Chapter 1 (Illegals)
Quirks: Unnamed Lizard Quirk (Rapt), Unnamed Flame Quirk (Moyuru)
Rapt: Eh? No way. I flew. I fell. Bam! Hospital.What kinda dumbass doesn't learn a lesson?
Moyuru: No doubt! Hey, any hot nurses in this joint?
Rapt: Gya ha ha! Get yourself hurt and find out.
Soga's two punkish friends who follow him around and generally cause mischief. Rapt's Quirk gives him his lizard appearance and Moyuru's Quirk gives him a small flame on top of his head.
- Curb-Stomp Battle: They and Soga are on the receiving end of one from Knuckle Duster in the first two chapters.
- Easily Forgiven: Played with. Koichi is fine chatting with them after they beat him up, but Pop☆Step still hates them for what they did to her.
- Good Smoking, Evil Smoking: Both are shown to be smokers, with Rapt even trying smoke while he's in the hospital.
- Healing Factor: Moyuru and Rapt himself imply that his Quirk allows him to heal his injuries quickly, even after being "smashed to pieces".

- In-Series Nickname: Moyuru is often referred to as just "Moyu" by his friends.
- Lizard Folk: Rapt is one due to his Quirk.
- Meaningful Name: Rapt is a dinosaur-man named "Raptor".
- One-Winged Angel: After taking Trigger, Moyuru grows bigger and his fire spreads all around his body, and Rapt becomes even more lizard-like and literally grows wings. Their transformations eventually wear off though.
- Playing with Fire: Moyuru, thanks to his Quirk.
- Reformed, but Not Tamed: In the first chapter they beat up Koichi and assault Pop☆Step. Later on, they're still punks but not nearly so bad and have started working with Knuckle Duster, even joining Soga in looking after Tamao.
- Smarter Than You Look: They're punks, but they're not stupid. Rapt, in particular, is intelligent enough to turn down Trigger after it nearly got him killed the last time he took it, even if it allowed him fly.
- Spell My Name with an "S": In Illegals Volume 1, Rapt's name is translated as "Raputo", while all future volumes refer to him as "Rapt".
- True Companions: With each other and Soga. Soga cares enough about them to risk his lofe for them, and they have, in turn, helped Soga out with issues. They become this with Tamao after they begin to watch over her with Soga as well.
- Villain Respect: Moyuru calls Koichi a "big man" when the vigilante strikes up a casual conversation with them, despite the fact that they attacked him.
Debut: Chapter 12 (Illegals)
The younger sister of police detective Naomasa Tsukauchi, and an upperclassman at Koichi's college. She's studying the hero system and the history of vigilantism for her college thesis. Her Quirk, "Polygraph", enables her to tell whether someone is lying or not by making physical contact with them.
- The Ace: When it comes to organizing and leading groups there isn't really a better ally to have then Makoto. She is very good at getting people to work together and while a bit manipulative she tends to make things better for everyone involved. She's also beautiful, kind, and an all-around fun person to be around.
- Beauty Mark: Has one on the left side of her jaw.
- But Now I Must Go: In chapter 58, she leaves Japan to study abroad in America.
- Go-Getter Girl: A college student who is working on her thesis, investigating the Naruhata vigilantes' activities, practically running Captain Celebrity's PR department, and helps manage the event where Pop☆Step makes her stage debut. If there's anything that needs organizing, Makoto's your woman.
- Living Lie Detector: Her Quirk legitimately makes her one, she just needs to be making physical contact. It can be fooled either by Exact Words or if the subject doesn't believe that they are telling a falsehood, such as when she outright asks Koichi if he's "The Hauler". Because he's not, he's "The Crawler".
- Meganekko: Though she alternates between glasses and contact lenses depending on the look she's going for.
- Ms. Exposition: In helping Koichi with his class work, she provides an infodump regarding the formation of the existing hero system.
- One Degree of Separation: Connected to the vigilantes through Koichi, the police through her brother, and the world of pro heroes through working part-time for Captain Celebrity.
- Rescue Romance: Starts to fall for Koichi after finding out he is the Crawler while being rescued from a runaway bus.
- Secret Keeper: Is this to Koichi's vigilante activities as the Crawler after being saved by him from a hijacked bus.
- Unwitting Instigator of Doom: Unbeknownst to her, her feelings for Koichi and desire for him to come with her on her travels ends up pushing Pop towards Number 6, allowing him to isolate Pop from her peers and lure her into a trap to turn her into the new Quinn Hachisuka.
- Wacky Marriage Proposal: When she comes back to Japan, she simply and flatly asks Koichi to come with her wherever she goes next. It's not quite a marriage proposal, but it's clear that's where she expects it to end up. She tells him to talk things over with Pop before making a decision.
Debut: Chapter 28 (Illegals)
Quirk: Unknown, Queen Bee (Formerly)
Knuckle Duster's daughter, a.k.a Kuin Hachisuka... Kinda. After a fight with her father over her performing at a concert, Tamao was lured astray by the Villain Factory, and was selected to be the new host of the Queen Bee, creating "Kuin Hachisuka" as seen in the main story. As of Kuin's defeat, and the Queen Bee's extraction, she's been staying in a hospital recovering.
- Antagonistic Offspring: Is this to Knuckle Duster while possessed by Kuin. While she isn't in complete control over herself as Kuin, flashbacks show that she and her father did have a rocky relationship, mostly over her interest in music. Even after he saves her from the Queen Bee, she still gets a kick by playing the guitar because he apparently hated it.
- Eye Scream: Implied. Knuckle Duster has to rip Queen Bee out of her eye socket, implying it drilled its way into her head via her eye, as she used to have two normal ones. She still wears an eye patch once she's hospitalized and it's all but spelled out that her left eye is entirely gone.
- Fan Disservice: Knuckle Duster rips her shirt open, giving the audience a good look at her bust, but he's doing this because he's trying to resuscitate her by shocking her back to life.
- Idol Singer: She wanted to be one, which her father didn't approve of. Circumstances conspired and prevented her from obtaining the dream, and it's not clear if she still wants to do it, even initially refusing to practice the guitar again until Soga tells her it will piss her dad off.
- Ill Girl: She's currently laid up in the hospital and in physical rehab. It's to be expected after a bunch of bees burrowed through her eye and Knuckle Duster beat her up before stopping her heart just to get rid of them.
- Near-Death Experience: Knuckle Duster stops the blood flow to her brain in order to free her from Kuin, but he is able to resuscitate her.
- Puppeteer Parasite: She fell victim to one, the Queen Bee that resided in her head.
- True Companions: Thanks to her dad asking them to look after her, Soga, Moyu, and Rapt slowly become hers as she's stuck in the hospital.
Debut: Chapter 59 (Illegals), Chapter 216 (Main Series)
A second-year classmate Eraserhead & Present Mic had when they attended U.A. High School. His Quirk, "Cloud", allows him to create various clouds.
- Ambiguous Situation: Something happened to him between the time he was in school and the present time of Vigilante. Exactly what happened is unclear until Chapter 64, which reveals that he tragically died during a villain attack. Even then, Chapter 253 of the main series casts that into doubt.
- Anime Hair: His hair is designed to look like a cloud, particularly with the way it's colored.
- Book Dumb: His teacher states that while his grades aren't great, his positive attitude and combat skill is enough for him to get by.
- Censor Steam: Does this for himself by making a cloud that acts as an "aesthetic that's censored just enough" when he needs to change during class.
- Character Death: While on his Work Studies with Aizawa, a giant villain named Garvey began to rampage through the town. The villain's destructive power lead to several buildings being brought down, one of which would have crushed a group of school children had Shirakumo not moved in to create a protective barrier of clouds over their heads. Unfortunately, he got to close to the destruction and is buried beneath a pile of rubble, leaving Aizawa as the only hero on the scene capable of defeating the large villain. Aizawa is able to do so, mainly due to Shirakumo giving him a Rousing Speech through his speaker. Except, he didn't actually do that; Aizawa just imagined that his own inner pep talk was coming from the speaker. As he finds out after his battle, Shirakumo had already been crushed to death, leaving Aizawa devastated at the loss.
- Chivalrous Pervert: He's doesn't hide his joy when he gets to see the nearly naked Midnight in her "Birthday Suit Style" costume. Still, he's a perfectly nice guy who's training to be a hero.
- Cloudcuckoolander: He's an odd duck for sure, whether it's causally stripping naked in class or potty training a kitten by having it wizz all over him.
- Doomed by Canon: Side conversations in the original series heavily implied that something terrible happened to Shirakumo before the events of the main story. As it turns out, Shirakumo was killed protecting a teacher and a group of schoolchildren while interning with Kayama and His Purple Highness.
- Early-Bird Cameo: He first appeared in Aizawa's small flashback in chapter 216 of the main series before he was wholly introduced in Vigilante. He can also be spotted in the second ending of the anime's fourth season, long before he was even mentioned in the anime.
- Establishing Character Moment: He introduces himself in Vigilantes by entering his class through a window, stripping naked because "wet underwear feels gross," and rescuing a kitten from the rain that Aizawa had previously left behind, establishing himself as a weird guy with a big heart.
- Foil: He is everything Aizawa isn't. He is confident, outgoing, personable and essentially a natural born hero, not unlike All Might, where Aizawa, as a teen, had big self-esteem issues, had a hard time seeing himself as a hero or even acting like one, and was not good at communicating and bonding with others outside of Mic. He is even introduced as one, since where as Aizawa can't bring himself to save a kitty left abandoned in the rain, Shirakumo saves it and bring it to school without thinking twice.
- Forgotten Fallen Friend: Averted. Shirakumo's death haunts Aizawa to the present day and is implied to have turned him from an Adorkable, timid guy to The Eeyore. When Tsukauchi reveals that the base of Kurogiri's Quirk is Shirakumo's, Aizawa is livid and it's Mic who has to tell him to calm down.
- Genki Guy: Shirakumo is friendly, excitable, and relentlessly energetic. Aizawa was bothered by this, but it also made him look up to Shirakumo.
- Goggles Do Nothing: Subverted. He wears his goggles to keep stuff like smoke and debris from getting to his eyes. He lends them to Aizawa when they're fighting a villain who can produce smoke with his Quirk, allowing Aizawa to disable him without worrying about having to shut his eyes. Aizawa sticks with the idea of using goggles in his future career as a Pro Hero.
- Heroic Sacrifice: He dies when he uses his clouds to protect a teacher and her kindergarten students from falling rubble, which allows it to fall and crush him instead.
- Meaningful Name: His last name refers to his quirk. "Shirakumo" (白雲) is literally translated as "White Cloud", as he has the power to summon clouds. Likewise, "Oboro" (朧) means "cloudy" or "hazy".
- Monkey King Lite: He's pretty clearly based on Sun Wukong. When in his hero costume, he wears a gi that looks a lot like the one worn by Son Goku (who's the most well-known example of the trope), uses a staff like Wukong and his headpiece resembles Wukong's Golden Ring Headband. He also has a pretty mischievous personality. The most obvious reference is his Quirk, which allows him to create a cloud that he can ride on like Wukong's nimbus cloud. He's also killed when he's crushed under a pile of fallen rubble, much like how Wukong was buried under a mountain. The only thing he lacks is a monkey motif, since there's more focus on his association with clouds due to his Quirk.
- Nice Guy: He brings a stray cat to school to protect it from the rain and also returns the umbrella that was originally shielding it from rain to its owner.
- Not Quite Dead: While he did indeed die on that fateful day, there seems to still be remnants of his old self left in Kurogiri, who is a Nomu made out of his corpse.
- Perpetual Smiler: His M.O. is to keep smiling no matter what, even when he screws up.
- Simple Staff: His primary weapon, which he often tips with his clouds.
- Solid Clouds: His Quirk allows him to create clouds dense enough for him to stand on.
- Steven Ulysses Perhero: His last name means "White Cloud" and he can produce clouds as his Quirk.
- Stock Shōnen Hero: He has all the trappings of one. Wild hair, a cheerful, goofy personality, and a strong, practical Quirk with a variety of applications.
- Tragic Bromance: With Eraserhead. Though always introverted and snarky, Shirakumo's unexpected death caused Eraserhead to become more outwardly confident, critical of other heroes, and combat-oriented. Also with Present Mic to a lesser extent, since Shirakumo's death mostly led Yamada to pick up the slack in becoming Aizawa's primary source of encouragement (although Mic's outer exuberance also seemed to become a bit more artificial after losing his friend).
- You Are Better Than You Think You Are: Whenever Aizawa was down, he and Mic would always be there to cheer him up and assure him that he's a much better hero than he takes himself for.
- You Gotta Have Blue Hair: Light blue and wispy, like a cloud against a blue sky.
Debut: Chapter 67 (Illegals)
The Marukane Event Department's manager after Makoto moved to America. He also has a hero license and an interest in Pop☆Step.
- Beware the Nice Ones: He's a really nice guy who can also kick some serious ass. Though, he isn't as nice as he acts.
- Be Yourself: His friends tell him to do this after Pop☆Step rejects him. He decides that they're right, and then kills them all, revealing his true identity as Number 6 to the audience.
- Defeat Means Friendship: He ends up up befriending the three thugs he beat up in Chapter 69, with Chapter 70 even showing them trying to cheer Nomura up after Pop☆Step rejects his Love Confession. He thanks them by killing them all.
- Foreshadowing: When he first lets his hair (pictured to the side), a strand of his hair falls in front of his face, and is shaped and situated exactly like Number 6's scar.
- In-Series Nickname: His friends call him "Rock", cause he's one rockin' dude!
- Meaningful Name: His name is a hint towards his true identity. His first name is Rokuro, and Roku is "6" in Japanese, while his last name is Nomura, or Nomura, to be more precise, reflecting Number 6's apparent proto-Nomu nature.
- Nice Guy: He's very kind and caring towards Pop☆Step and others in general. Despite being a licensed hero, he doesn't actually work as a pro, he just got licensed so that he can be a legal version of a vigilante. Number 6 crafted this personality specifically to get Pop☆Step to like him.
- Not Good with Rejection: He takes Pop☆Step rejecting his Love Confession pretty hard. His friends try to cheer him up by giving him advice and playfully ribbing him, but killing them is what actually makes him feel better.
- Stronger Than They Look: He looks rather meek and mild, but is strong enough to handle three thugs twice his size. Justified, as he's a registered hero on the side, and because he's really Number 6 in disguise.
- Walking Spoiler: He's really Number 6 in disguise.
